Cyril V. Jackson (5 December 1903 – February 1988) was a South African astronomer, known for discovering 72 asteroids and a number of comets.
After the war he was director of the Yale-Columbia Southern Observatory (YCSO) station in Johannesburg (IAU code 077), which had been established by Yale University in the 1920s.
[1] Columbia University subsequently collaborated in that venture and the operation became known as the Yale-Columbia Southern Observatory (YCSO, Inc. was formally created in 1962).
This Yale-Columbia telescope was given to the Australian National University in July 1963, and was destroyed in the 18 January 2003 firestorm that devastated Mount Stromlo.
In 1963, Yale reopened its Columbia Southern Observatory at El Leoncito, Argentina (IAU code 808), and he served as its director there until 1966, when he retired.
